“…Italy; (Scalici et al, 2010)) and there are still wide areas environmentally suitable for invasion worldwide . Likewise, P. leniusculus is spreading over the Iberian Peninsula, with wide areas available for invasion in this territory and also worldwide (Capinha et al, , 2012. On a macroscale, these two species have relatively different environmental preferences but their distributions clearly overlap in some areas, such as the studied river stretch.…”

a b s t r a c tRed swamp crayfish (Procambarus clarkii) and signal crayfish (Pacifastacus leniusculus) are two invasive freshwater species with a worldwide distribution. The objective of this work was to investigate how the two species move and use space in an area of recent coexistence. Simultaneously, we test the use of new tools and indices to describe their movement patterns. To accomplish this we performed a radiotracking program within a river-type habitat during two different periods (September/October 2010 and June/July 2013). We used spatial analysis tools to map crayfish radio-location data with and without accounting for the curvature of the river. To assess the consistency of the direction of movement and of the distances traveled by crayfish, two indices were developed. To assess the habitat preferences of each species we applied Ivlev's Electivity Index and the Standardized Forage Ratio. Movement of P. clarkii and P. leniusculus differed. The average detected movement was 8.8 m day −1 for P. clarkii and 17.5 m day −1 for P. leniusculus. However, crayfish behavior ranged from almost complete immobility -sometimes during several days -to large movements, in half a day, up to a maximum of 255 m for P. clarkii and 461 m for P. leniusculus. The proportion of upstream or downstream movements was independent of the species and both species displayed no preference for either direction. The indices of consistency of movement showed a large interindividual variation. Species and period (2010 or 2013) affected the mean daily distance traveled, maximum observed distance from location of release and percentage of observations under vegetation cover. The Ivlev's Electivity Index and the Standardized Forage Ratio presented similar results. P. clarkii showed a preference for pool areas with riparian vegetation cover while P. leniusculus preferred riffle and pool areas with riparian vegetation cover. Our work provided new and valuable data for modeling the active dispersal of these two problematic invaders in a context of coexistence.

“…Posteriorly, these data were resampled to match the remaining variables in R. To avoid collinearity among variables, Pearson correlation coefficients were calculated for all pairs or predictors and the environmental variables included were the ones not highly correlated (r < 0.83). Several published papers refer distinct r values to define high correlations, for example r < 0.80 (Gallardo and Aldridge, 2013), r < 0.85 , r < 0.80 (Capinha et al, 2012) and some studies indicate that variables with −0.70 < r < 0.70 should be excluded (Domisch et al, 2013following Green, 1979. In this study only one pair of pairwised variables had an r outside this range being the remaining lower than 0.7.…”

Please cite this article in press as: Gama, M., et al., Predicting global habitat suitability for Corbicula fluminea using species distribution models: The importance of different environmental datasets. Ecol. Model. (2015), http://dx. a b s t r a c tNiche-based models (NBMs) are increasingly being used to predict the biological distribution of species, as well as the importance of different environmental variables on their habitat adequability. Here, we investigate the reliability of these models in predicting habitat suitability for Corbicula fluminea, an important freshwater bivalve invasive species. In order to determine the influence of topographic vs. climatic variables, three datasets were used: (1) CorbiculaTOPO with topographic variables (altitude, slope and a compound topographical index); (2) CorbiculaMIX, combining climatic (annual mean temperature, mean temperature of warmest quarter, mean temperature of coldest quarter and annual precipitation) and topographic variables and (3) CorbiculaCLIM with only the climatic variables. Nine different types of models, implemented in BIOMOD2, were used and an ensemble of NBMs was built. We aimed to know how climatic suitability for these invaders changes when using different datasets of environmental variables; if the predictive reliability is similar between datasets; and which environmental variables better explain habitat adequability. Model performance was very similar between CorbiculaMIX and Corbicula-CLIM. CorbiculaTOPO was the dataset with the least accurate predictions. Mean temperature of the coldest quarter and altitude were the variables that influenced C. fluminea distribution the most. The use of an ensemble of predictions allowed us to clearly identify areas with potential to be invaded by the bivalve, in which records are not yet detected. This information can be used in management, to implement measures to delay or prevent invasions, as well as for the identification of the environmental variables that favor that invasive potential.

“…Species distribution data alone provides no information on how a species will respond to new climatic combinations and, thus, correlative predictions should be avoided for non-analog climates (Fitzpatrick and Hargrove 2009;Capinha et al 2012). Moreover, because of the geometric nature of alpha-shapes, the new climatic combinations are likely to fall outside the species niche.…”

Aedes aegypti is the main vector of dengue and a number of other diseases worldwide. Because of the domestic nature of this mosquito, the relative importance of macroclimate in shaping its distribution has been a controversial issue. We have captured here the worldwide macroclimatic conditions occupied by A. aegypti in the last century. We assessed the ability of this information to predict the species' observed distribution using supra-continental spatially-uncorrelated data. We further projected the distribution of the colonized climates in the near future (2010-2039) under two climate-change scenarios. Our results indicate that the macroclimate is largely responsible for setting the maximum range limit of A. aegypti worldwide and that in the near future, relatively wide areas beyond this limit will receive macroclimates previously occupied by the species. By comparing our projections, with those from a previous model based strictly on species-climate relationships (i.e., excluding human influence), we also found support for the hypothesis that much of the species' range in temperate and subtropical regions is being sustained by artificial environments. Altogether, these findings suggest that, if the domestic environments commonly exploited by this species are available in the newly suitable areas, its distribution may expand considerably in the near future.
